Answer:

x = 28/3

Step-by-step explanation:

We can solve this problem by using similar triangles:

Both of these triangles have a 90 degree angle and they share angle A, meaning that they are similar by AA similarity.

Now we can set up ratios and solve:

13/7 = (x+8)/x

multiply both sides by x:

13x/7 = x+8

Multiply both sides by 7:

13x = 7x + 56

move the 7x over and divide by 6:

6x = 56

x = 28/3

Answer:

9 1/3 or 9.3333333333

Step-by-step explanation:

Triangle ABC is similar to Triangle ADE because they are proportional. It is a 7:13 ratio as shown by segments CB and ED.

Therefore, the ratio from AB to AD would also have to be 7:13. The ratio as shown by the picture is x:x+8. Therefore x:x+8=7:13.

Now you put this in fraction form. $\frac{x}{x+8}$ = $\frac{7}{13}$ You multiply both sides by X+8 and get X= $\frac{7x+56}{13}$ . Now you multiply both sides by 13 and get 13X=7x+56. Now you have cleared the fractions so it looks neater. Next, you subtract both sides by 7x and get 6x=56. Finally you divide both sides by 6 and get x=9 1/3

Find the sum of the first 25 terms of a geometric sequence where the first term is 177,147 and the common ratio is .

puteri [66]

Here's the relevant formula:

1 - r^n
nth partial sum = a* ------------
1 - r
1 - r^25
Here, the 25th partial sum is 177147 *-------------
1 - r

Unfortunately, you haven't yet shared the value of the common ratio. Find that value and substitute it for r in the above expression.

Can someone help me? With all the problems and with work

Answer:

5.006

41.056

31.289

51.977

7.884

Step-by-step explanation:

1) sin x = opposite side / hypotenuse

sin 24.3° = 2.06 / hyp

hyp = 2.06 / sin 24.3 = 5.0059006616019108320511866543651

rounding to 3 significant figures

= 5.006

2)cos x = adjacent side / hypotenuse

cos 47 = 28 / x

x = 28 / cos 47 = 41.055817197909497891901840157945

= 41.056

3) cos x = adjacent side / hypotenuse

cos 56.1 = x / 56.1

x = 56.1 * cos 56.1 = 31.289500613760617368691451544764

= 31.289

4) tan x = opposite side / adjacent side

tan 68 = x / 21

x = 21 * tan 68 = 51.9768239217422123300402781676

= 51.977

5) sin x = opposite side / hypotenuse

sin 21 = x / 22

x = 22 * sin 21 = 7.8840948899966060166510313670963

= 7.884

1) Find an equation of the line that passes through thr pair of points (-5,-9) and (2,-7).

Yuki888 [10]

1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is $m=\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }$ , so in this case, it is $m=\frac{ (-7) - (-9) }{ 2 - (-5) }$ , which comes to $\frac{2}{7}$ . Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y= $\frac{2}{7}$ x- $\frac{53}{7}$ .

2. Use the same process as in question 1 to find:
y=-7x+11
